What This Document Is
This document is a student exploration activity, “Coral Reefs 2 – Biotic Factors,” designed for a Biological Concepts (BIO 101) course at Murray State University. It uses a simulation (Gizmo) to investigate how living organisms and their interactions impact the health and stability of coral reef ecosystems. The activity builds upon a prior exploration of abiotic (non-living) factors affecting reefs.
Why This Document Matters
This exploration is valuable for students learning about ecology, specifically how complex ecosystems function. It’s used to understand the interconnectedness of species within a coral reef and the consequences of disruptions like invasive species or overfishing. Students will benefit from this activity when studying population dynamics, food webs, and conservation biology. It provides a practical, visual way to model ecological principles.
Common Limitations or Challenges
This document is a guided exploration within a simulation. It doesn’t provide a comprehensive textbook treatment of coral reef ecology. It focuses on specific scenarios (fishing, disease) and doesn’t cover all possible biotic interactions. The simulation is a model, and real-world ecosystems are far more complex. This preview does not provide answers to the questions within the Gizmo; it’s designed to help you determine if the full activity will be a useful learning tool.
What This Document Provides
The full document includes:
* A simulation environment to manipulate biotic factors (fishing levels, disease presence).
* Data collection tools to track population changes of various reef organisms.
* Guided questions prompting students to make predictions, observe results, and explain ecological relationships.
* Vocabulary definitions for key terms like “biotic factor,” “invasive species,” and “black band disease.”
* Exploration of the effects of fishing regulations on reef health.
This preview *does not* include the simulation itself, the answers to the questions, or the full data sets generated during the activity. It is a preview to help you understand the scope and purpose of the student exploration.
